一、关于竖直上抛运动公式的讨论在高中物理课本中,分析匀减速运动时,一般都要把竖直上抛物体的运动作为匀减速运动的实例而引入,在这里让a=g,S=h,代入匀减速运动的公式:V_1=V_0-at,S=V_0t-1/2at~2, 即得到:V_1=V_0-gt ① h=V_0t-1/2gt~2 ②但在应用此公式解决问题时,经常有人提出下面两个问题: 1.为什么公式①和②不仅适用于物体上抛过程的匀减速运动,同时也适用于物体抛至最高点后,再落下的匀加速运动呢? First, the discussion on the vertical throwing motion formula In high school physics textbook, analysis of uniform deceleration, generally have to put the vertical motion of the parabolic body as an example of uniform deceleration introduced here a = g, S = h, into the uniform deceleration motion formula: V_1 = V_0-at, S = V_0t-1 / 2at ~ 2, that is: V_1 = V_0-gt ① h = V_0t- 1 / 2gt ~ 2 ② However, Formulas solve the problem, it is often asked the following two questions: 1. Why formula ① and ② not only applies to the object on the process of uniform deceleration movement, but also applies to the object after the highest point, and then falling uniform acceleration it ?
